- Enter CIELAB values — L* (0-100), a* (-128 to 127), and b* (-128 to 127) — in the input fields
- Or use the color picker to visually select a color and auto-fill LAB values
- Adjust the Delta E threshold to control how broadly the tool searches for matches
- View the closest Pantone color matches ranked by Delta E 2000 similarity
- Copy color values in multiple formats (LAB, HEX, RGB, CMYK) or save to your collection
LAB to Pantone Converter Use Cases
- Convert spectrophotometer LAB readings to the nearest Pantone spot color
- Match ICC profile target colors to Pantone for print production
- Find Pantone equivalents for quality-control LAB measurements
- Bridge lab-measured colors to Pantone references for ink and material formulation
Why Use LAB for Color Conversion?
CIELAB (L*a*b*) is the standard color space for color measurement instruments and ICC profiles. Because LAB is perceptually uniform, the Delta E 2000 distance between any two LAB values directly represents how different they look to the human eye. This converter uses Delta E 2000 — the most advanced color-difference formula — to find the closest Pantone match.
FAQs
What is the LAB to Pantone converter?
The LAB to Pantone converter takes CIELAB (L*a*b*) color coordinates and finds the closest Pantone spot color using the Delta E 2000 perceptual color-difference formula. This is ideal for matching instrument-measured colors to standardized Pantone references.
How is LAB different from RGB?
RGB is a device-dependent model tied to screen hardware. LAB is device-independent and perceptually uniform — equal numerical steps produce equal perceived color changes. LAB is the standard for color measurement, ICC profiles, and Delta E calculations.
Why convert LAB to Pantone?
Color measurement instruments (spectrophotometers, colorimeters) output LAB values. Converting those readings to Pantone gives you a standardized, universally recognized color reference for print, packaging, textiles, and coatings.
What are the valid ranges for LAB values?
L* (Lightness) ranges from 0 (black) to 100 (white). a* ranges from negative (green) to positive (red), typically -128 to 127. b* ranges from negative (blue) to positive (yellow), typically -128 to 127.
